    GUID-081170508.jpg

    The Hands Free Module (HFM) (3) (also known as the Bluetooth™ module) is found in vehicles equipped with the optional Uconnect® Hands-Free System. This module is located beneath the instrument panel and above the steering column. The HFM hardware and circuitry is contained and protected within a molded black plastic housing that has two integral mounts (2) and an integral locating pin (1). The HFM is positioned to a stamped metal steering column mounting bracket by the locating pin, then secured to the bracket by two screws.

    The HFM has three integral connector receptacles that are oriented toward the dash panel when it is installed in the vehicle. The two largest receptacles (5 and 6) connect the HFM to the vehicle electrical system through dedicated take outs and connectors of the instrument panel wire harness. The smallest connector (4) accepts a Universal Serial Bus (USB) cable connector that connects the HFM to the Radio Receiver Module (RRM) (also known as the radio or the head unit).

    The internal circuitry of the HFM includes a microcontroller, flash memory and a Bluetooth™ module. The module also includes sophisticated Voice Recognition (VR) software. The HFM software is flash programmable.

    The HFM cannot be adjusted or repaired and, if damaged or ineffective, the entire HFM must be replaced.

    3. Remove the knee blocker from the instrument panel steering column opening. (Refer to 23 - Body/Instrument Panel/KNEEBLOCKER - Removal) .
    5. Remove the brake pedal assembly from the dash panel (4). (Refer to 05 - Brakes/Hydraulic/Mechanical/PEDAL(S) , Brake and/or Accelerator - Removal).

      NOTE:

      One of the HFM mounting screws is concealed between the forward (connector) side of the module and the dash panel.

    7. Remove the two screws (2) that secure the Hands Free Module (HFM) (1) to the underside of the instrument panel column support bracket.
    9. Lower the HFM far enough to access and disconnect the three wire harness connections (5) from the module connector receptacles.
    11. Remove the HFM from above the steering column (3) and under the instrument panel.
